Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchanger tube assembly, and in particular relates to a heat exchanger tube support device. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] The tube structure of the heat exchanger is complex, and the tube body needs to be assembled when the heat exchanger is used. When assembling the tube body, the fixing angle of the tube body is complex and changeable, and it is often necessary to place the tube body at a suitable angle, and perform engineering operations such as assembly and connection on the tube body. Since the tube body is mostly curved and the bending angles are different, it is difficult for the existing support device to move the tube body in multiple postures, which reduces the flexibility of the tube body movement and is not conducive to the efficient assembly of the tube body. In addition, the existing support mechanism mostly supports or clamps the tube body on the outside of the tube body, which reduces the assembly space on the outside of the tube body and limits the assembly efficiency of the tube body. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the utility model provides a heat exchanger tube body support device, which supports the tube body of the heat exchange tube by extending the inner tube tightening device into the tube body of the heat exchanger and uses a telescopic rod to expand the tightening block to abut against the inner wall of the tube body, thereby facilitating the movement and adjustment of the heat exchange tube body and supporting the tube body inside the tube body to facilitate the assembly of the outer wall of the tube body.

[0005] The utility model is realized by the following technical solutions:

[0006] A heat exchanger tube support device includes a movable frame, a support rod and an in-tube tightening device. A movable wheel is installed at the bottom of the movable frame to facilitate the movement of the movable frame. The support rod is horizontally installed to the top of the movable frame. The in-tube tightening device includes a prism body and a tightener fixed to the side of the prism body. The tighteners are provided in multiple groups and are evenly distributed along the circumferential direction of the prism body. The tighteners include a mounting plate, a tightening block, a support rotating rod, a pull rod, a slider and a telescopic rod. The mounting plate is fixed to the side wall of the prism body. A slide groove for the slider to slide is provided on the mounting plate. The tightening block is hinged to the mounting plate through the support rotating rod. The tightening block and the slider are also connected by a pull rod. The telescopic rod is installed on the mounting plate and can drive the slider to slide along the extension direction of the slide groove to drive the tightening block to abut against the inner wall of the tube body to achieve internal support for the tube body.

[0007] Furthermore, the support rod includes a first rod body and a second rod body, and the first rod body can slide relative to the second rod body in the extension direction of the second rod body, so that the first rod body drives the inner tube tightening device to extend into the tube body of the heat exchanger.

[0008] Furthermore, the pull rod includes a first frame and a second frame, the first frame is hinged to the tightening block, the second frame is hinged to the slider, the second frame is protruding with an insertion rod, a slot for accommodating the insertion rod is opened in the first frame, a spring is sleeved on the outside of the insertion rod, and the spring is located between the first frame and the second frame, so that the pull rod has elastic expansion and contraction properties, which helps the tightening block to elastically abut against the inner wall of the tube body, thereby improving the protection of the tightening block and the tube body.

[0009] Furthermore, a protective pad is attached to the outer side of the tightening block, and the protective pad is made of a flexible material to protect the inner wall of the tube body.

[0010] Furthermore, the outer side of the protection pad is an arc-shaped surface, which increases the contact area between the protection pad and the inner wall of the tube body and improves the protection performance.

[0011] Furthermore, a rotating mechanism is installed between the support rod and the mobile frame, the rotating mechanism is fixed to the top of the mobile frame, and the rotating mechanism can drive the support rod to rotate.

[0012] Furthermore, a mounting bracket is provided on the top of the movable frame, and a camera is installed on the mounting bracket. The camera points to the tensioning device in the tube to observe the expansion and contraction activities of the tensioning device in the tube.

[0013] Furthermore, a mounting bracket is provided on the top of the movable frame, and a trimming machine is installed on the mounting bracket. The trimming machine can process the end face of the tube body to achieve correction of the end face of the tube body.

[0014] Furthermore, the supporting device also includes a control system, and the supporting rod and the in-tube tightening device are both connected to the control system signal.

[0031] Finally, it should be noted that when a component is referred to as being "located" or "set on" another component, it can be on the other component or there can be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be an intermediate component at the same time.

[0032] like Figures 1 to 8 A heat exchanger tube support device is shown, comprising a movable frame 1, a support rod 2 and a tube inner tightening device 3. A movable wheel 11 is installed at the bottom of the movable frame 1 to facilitate the movement of the movable frame 1. The support rod 2 is horizontally installed to the top of the movable frame 1. The in-tube tightening device 3 includes a prism body 31 and a tightener 32 fixed to the side of the prism body 31. The tightener 32 is provided with multiple groups and is evenly distributed along the circumferential direction of the prism body 31. The tightener 32 includes a mounting plate 321, a tightening block 322, a supporting rotating rod 323, a pulling rod 324, a sliding block 325 and a telescopic rod 326. The mounting plate 321 is fixed to the side wall of the prism body 31. The mounting plate 321 is provided with a sliding groove 3211 for the sliding block 325 to slide. The tightening block 322 is hinged to the mounting plate 321 through the supporting rotating rod 323. The tightening block 322 and the sliding block 325 are also connected by the pulling rod 324. The telescopic rod 326 is installed on the mounting plate 321 and can drive the sliding block 325 to slide along the extension direction of the sliding groove 3211, so as to drive the tightening block 322 to abut against the inner wall of the tube body 5, thereby realizing internal support for the tube body 5.

[0033] In one embodiment, first, the mobile frame 1 is moved to the vicinity of the installation location of the tube body 5 of the heat exchanger, so that the support rod 2 is aligned with the tube body 5 of the heat exchanger. Then, the mobile frame 1 is pushed toward the tube body 5, so that the tube inner tightening device 3 installed at the end of the support rod 2 extends into the interior of the tube body 5. Finally, the telescopic rod 326 is controlled to extend the telescopic rod 326, and the telescopic rod 326 extends to push the slider 325 to move along the slide groove 3211 toward the tightening block 322. The slider 325 drives the tightening block 322 to move away from the prism body 31 under the limiting action of the support rotating rod 323 through the pull rod 324, until the outer wall of the tightening block 322 abuts against the inner wall of the tube body 5. Multiple tighteners 32 move synchronously, thereby realizing the internal tightening operation of the tube body 5, so as to facilitate the assembly of the tube body 5 of the heat exchange tube.

[0034] like Figures 1 to 3 As shown, it should be noted that the tube body 5 in the accompanying drawings is only the end of the tube body 5. Since the tube body 5 of the heat exchanger is relatively large, only a section of the tube body 5 is cut out in the accompanying drawings as an indication, that is, the tube body 5 shown in the accompanying drawings is not the complete tube body 5 of the heat exchanger.

[0035] Preferably, the support rod 2 includes a first rod body 21 and a second rod body 22. The first rod body 21 can slide relative to the second rod body 22 in the extension direction of the second rod body 22, so that the first rod body 21 drives the tube tightening device 3 to extend into the tube body 5 of the heat exchanger.

[0036] In one embodiment, when the in-tube tightening device 3 needs to be extended into the interior of the tube body 5, after the support rod 2 is aligned with the tube body 5, the first rod body 21 can be controlled to move relative to the second rod body 22, so as to extend the in-tube tightening device 3 into the interior of the tube body 5 without moving the mobile frame 1. It should be noted that the movement of the first rod body 21 relative to the second rod body 22 can refer to the existing telescopic device, that is, the support rod 2 can be telescopic, so that the in-tube tightening device 3 can be extended into the tube body 5. The telescopic principle and telescopic structure of the support rod 2 are conventional technologies and will not be repeated here.

[0037] Preferably, the pull rod 324 includes a first frame 3241 and a second frame 3242, the first frame 3241 is hinged to the tightening block 322, the second frame 3242 is hinged to the slider 325, the second frame 3242 is protruded with an insertion rod 3243, a slot for accommodating the insertion rod 3243 is opened in the first frame 3241, a spring 3244 is sleeved on the outside of the insertion rod 3243, and the spring 3244 is located between the first frame 3241 and the second frame 3242, so that the pull rod 324 has elastic expansion and contraction properties, which helps the tightening block 322 to elastically abut against the inner wall of the tube body 5, thereby improving the protection of the tightening block 322 and the tube body 5.

[0038] In one embodiment, the insertion rod 3243 of the second frame 3242 is inserted into the slot of the first frame 3241, so that the first frame 3241 can move relative to the second frame 3242 in the extension direction of the second frame 3242, and the first frame 3241 and the second frame 3242 are connected by a spring 3244, so that the pull rod 324 has elasticity. When the pull rod 324 pulls the tightening block 322 so that the tightening block 322 abuts against the inner wall of the tube 5, when the slider 325 pulls the pull rod 324 again, the spring 3244 in the pull rod 324 is deformed to protect the tightening block 322 and the tube 5.

[0039] Preferably, a protective pad 3221 is attached to the outer side of the tightening block 322 , and the protective pad 3221 is made of a flexible material to protect the inner wall of the tube body 5 .

[0040] Preferably, the outer side of the protection pad 3221 is an arc-shaped surface, which increases the contact area between the protection pad 3221 and the inner wall of the tube body 5 and improves the protection performance.

[0041] Preferably, a rotating mechanism is installed between the support rod 2 and the mobile frame 1 , the rotating mechanism is fixed to the top of the mobile frame 1 , and the rotating mechanism can drive the support rod 2 to rotate.

[0042] Preferably, a mounting bracket 4 is further provided on the top of the mobile frame 1, and a camera 41 is installed on the mounting bracket 4. The camera 41 points to the inner-tube tightening device 3 to observe the expansion and contraction activities of the inner-tube tightening device 3.

[0043] Preferably, a mounting bracket 4 is further provided on the top of the mobile frame 1 , and a trimming machine is installed on the mounting bracket 4 . The trimming machine can process the end face of the tube body 5 to achieve correction of the end face of the tube body 5 .

[0044] In one embodiment, the trimmer is used to grind the end face of the tube body 5 of the heat exchanger. When the tube body 5 of the heat exchanger is assembled, the end face of the tube body 5 is often uneven. The trimmer can be abutted against the end face of the tube body 5, and then the rotating mechanism is started to rotate the tube body 5 so that the trimmer can trim the end face of the heat exchange tube. It should be noted that the rotating mechanism can be an electric rotating machine. The rotating mechanism and the trimmer are both existing technologies, and the principles of the rotating mechanism and the trimmer are not described in detail here.

[0045] Preferably, the support device further comprises a control system, and the support rod 2 and the in-tube tightening device 3 are both connected to the control system by signal. The control system can electronically control the support rod 2, the rotating mechanism and the telescopic rod 326.

[0046] When the above-mentioned heat exchanger tube body supporting device is adopted, the tube body 5 of the heat exchanger is supported by extending the inner tube tightening device 3 into the tube body 5 of the heat exchanger, and the tightening block 322 is stretched open by the telescopic rod 326 to abut against the inner wall of the tube body 5, so as to facilitate the movement and adjustment of the heat exchange tube body 5, and support the tube body 5 inside the tube body 5, so as to facilitate the assembly of the outer wall of the tube body 5.

[0047] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
